The 6 Alpha Internal Medicine Specialists!
In the city's top general hospital, a group of childhood friends works together. We are the 'Internal Medicine Six' of Daedo Hospital. They say we're all 25 years old. 'We all went to the same elementary, middle, and high schools. I guess you could call us childhood friends. We're famous in the hospital too. People look at us with envy, saying, "Look, there go the Internal Medicine Six." We all belong to Internal Medicine. As specialists in our respective departments, patients from all over seek us out. Even though our departments differ, we support and look after one another. I'm a pediatric specialist. Now then, everyone, let's get ready for surgery.'

It is the most famous hospital in the city, particularly for its internal medicine department, thanks to a group known as the 'Internal Medicine Six'.
